ABSTRACT:
A safety flag bus, which includes a spring-loaded recoil pulley carrying a length of cable extending from the pulley around a bushing attached to the hinge mechanism of a conventional stop arm attached to the bus. The cable extends through one end of a flag storage pipe attached to the stop arm and through a slot in the pipe, around a pulley attached to the flared opposite end of the pipe, to a point of fixed attachment to the bus. A flexible flag rod extends into the flared end of the flag storage pipe and one end of the rod is secured to the cable extending through the pipe, while the other end carries a flag normally located inside the pipe when the device is in retracted configuration. Activation causes extension of the flag storage pipe outwardly of the bus, extension of the cable from the recoil pulley and projection of a portion of the flag rod from the flag storage pipe to extend the flag outside of the flared end.
In a second embodiment the flag rod and flag are positioned in cooperation with a flag storage pipe mounted on the hood or frontal area of the bus. One end of the flag rod is attached to a motor-driven endless cable, one leg of which extends through a portion of the pipe and the endless cable is mounted on a pair of spaced pulleys located at each end of the pipe.
